    Google redirect browser hijack virus

    I have caught the virus that seems to be going around lately (and it's not the swine flu.

    Google searches in Firefox (3.5.5) are often being redirected to arbitrary sites, including casinos, alternate search engines, and adware sites.

    I have scanned with Kaspersky, MBAM, and SuperAntiSpyware - each one claims to have found and fixed one or two items, but the problem persists.

    I have attached the two AVZ logs, and the HiJackThis log.

    Thanks in advance for your help.

    Hello,

    Close/disable all the applications excluded AVZ and Internet Explorer.

    - Disconnect your PC from network (internet/intranet)
    - Disable antivirus, firewall and other memory resident security tools
    - Disable System Restore

    -Fix with Hijackthis
    Код:
    F2 - REG:system.ini: UserInit=C:\WINDOWS\system32\userinit.exe
    O2 - BHO: (no name) - {06849E9F-C8D7-4D59-B87D-784B7D6BE0B3} - (no file)
    O2 - BHO: AskBar BHO - {201f27d4-3704-41d6-89c1-aa35e39143ed} - C:\Program Files\AskBarDis\bar\bin\askBar.dll
    O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)
    O3 - Toolbar: Foxit Toolbar - {3041d03e-fd4b-44e0-b742-2d9b88305f98} - C:\Program Files\AskBarDis\bar\bin\askBar.dll
    - Execute following script
    Код:
    begin
    SearchRootkit(true, true);
    SetAVZGuardStatus(True);
    ClearQuarantine;
     QuarantineFile('C:\WINDOWS\C-B.scr','');
     DelBHO('{3041d03e-fd4b-44e0-b742-2d9b88305f98}');
     DelBHO('{201f27d4-3704-41d6-89c1-aa35e39143ed}');
     DeleteFile('C:\Program Files\AskBarDis\bar\bin\askBar.dll');
     DeleteFile('c:\62822259db295d363cc19d\wgasetup.exe');
     DeleteFileMask('c:\62822259db295d363cc19d','*.*',true);
     DeleteDirectory('c:\62822259db295d363cc19d');
    BC_ImportAll;
    ExecuteSysClean;
    BC_Activate;
    SetAVZPMStatus(True);
    RebootWindows(true);
    end.
    If the system after reboot would try to install any unknown hardware, abort the installtion and remove unknown hardware over hardware manager

    After reboot:

    execute following script
    Код:
    begin
    CreateQurantineArchive('C:\quarantine.zip');
    end.
    - Clean Temp-Maps, Cache of Browsers, Recycler. Use Windows service tool cleanmgr or CCleaner or ClearProg
    - Upload the C:\quarantine.zip over the link Upload quarantined files on the top of this page.
    - Make new logs and attach them to the new posting.

    Thank you for your advise so far. I have followed the procedures you suggested, but the problem persists.

    I will start from the beginning of "the rules" again, with running Dr. Web Cure It, and then generating the logs and posting them. I expect that I should have the new data within a few hours, depending on the time for the complete scan.

    Here is the latest news and log files:

    1. I cannot boot the computer into safe mode - it BSODs every time.
    2. In normal mode I run Symantec AntiVirus - it reports clean.
    3. In normal mode I run Kaspersky - no threats found.
    4. In normal mode I run Dr. Web CureIt - it reports BackDoor.Tdss.565 in memory (eliminated), and it finds BackDoor.Tdss.1133 in C:\Windows\system32\drivers\iaStor.sys . It attempts to cure it, but it loops indefinitely on the cure attempt (the driver is seemingly loaded and cannot be modified while in use).

    Given that the other two anti-virus products don't find the backdoor, and Dr. Web does, it could be a false positive, or Dr. Web is smarter in this case.

    I have uploaded the previous quarantine.zip, and am attaching the latest AVZ and HiJackThis scans.

    I hope you are able to solve this. Thanks in advance.

    The logs seems to be clean. Remove Superantispyware and don't use any other antivirus excepted installed one.
    Replace file C:\Windows\system32\drivers\iaStor.sys using recovery console from original Windows CD
    Make a log of gmer: http://virusinfo.info/showthread.php?t=51878

    The problem is fixed with replacing iaStor.sys.
    I have attached the gmer log.

    Thank you very much for your assistance. It is much appreciated.

    Hello,

    your log seems to be clean.

    But you have to upgrade your antivirus solution. If you'd like to stay by Norton - use the version 2010.
    Look the last test of AV-Comparatives
